Canon RF 50mm f/1.2L USM Aperture Series: Beaver Pond Beaver Trail Through Reeds
See my Canon mirrorless wishlist.
This series evaluates performance of the Canon RF 50mm f/1.2L USM for its superb correction of aberrations. As part of that, a 4-frame focus stack is included, consisting of three frames at f/10 and one frame at f/8 (the most distant frame).
Canon RF 50mm f/1.2L USM Aperture Series: Beaver Pond Beaver Trail Through Reeds
Includes images up to full camera resolution from f/1.2 through f/10 plus a 4-frame focus stack along with a discussion of why the Canon RF 50mm f/1.2L USM makes a superb lens for focus stacking.
The path through the reeds and several others show routes taken by the resident beaver.
